Match Pair Sets

A sandwich ELISA was performed using the anti-CTLA-4 mAbs RF16011, RF16012, RF16013, as the capture antibodies for the CTLA-4 extracellular domain antigen with HRP-labeled Risk-Free anti-CTLA-4 mAbs as the detection antibodies.

Risk-Free™ Mouse Monoclonal CTLA-4 Products

ProSci’s Risk-Free™ antibodies are monoclonal antibodies made to improve in vivo studies. Unlike antibodies developed using proteins made in yeast or bacteria, Risk-Free™ CTLA-4 antibodies are developed with antigens expressed in mammalian cell lines, giving the most native post-translational modifications to the protein. Risk-Free™ means they are guaranteed to work for their approved applications.

Risk-Free™ Mouse Monoclonal CTLA-4 Set

ProSci’s Risk-Free™ Sets consists of several mAbs with different binding features allowing selection of the best clone.

Risk-Free™ Single Domain Monoclonal CTLA-4 Products

Llama single domain antibodies (sdAbs) offer unique characteristics amenable to many applications. These sdAbs demonstrate low nanomolar binding affinity and can be used for the various applications. Note: CTLA-4 antibody should be stored in working aliquots at -20 °C, stable for up to one year. As with all antibodies, care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures. Please contact us to discuss Single Domain Monoclonal CTLA-4 projects.

Additional Antibody CTLA-4 Products

Monoclonal antibodies are highly specific and recognize only one epitope on an antigen which generates consistent performance in quantitative detection applications regardless of production batch. Polyclonal antibodies have high affinity and recognize different epitopes on a specific antigen. Note: These antibodies can be stored at -20˚C and are stable for up to one year. Antibodies should not be exposed to prolonged high temperatures.
